New signings Jordan Baldwinson, Pauli Pauli and Justin Horo are in the Wakefield squad for the Boxing Day friendly against Leeds.
The first match in the build-up to the 2018 season takes place at Belle Vue, with kick-off at 11.30am.
Baldwinson will go up against his former club, while it will be a first opportunity for fans to see forward Pauli, signed on a one-year deal from Newcastle Knights in the NRL.
Former Catalans back-rower Horo is the club’s only other addition for 2018, with hooker Tyler Randell having already joined the club back in August.
Trinity are currently on the look out for a new assistant coach, following the departure of head of rugby John Kear to Bradford.
They have lost six players this off-season, including Mitch Allgood (St George), Michael Sio (released) and Sam Williams (Canberra).
